Ranking fuzzy data envelopment analysis based on statistical data and staticʹs confidence interval

Data envelopment analysis (DEA) is a non-parametric technique to measuring the relative efficiency of decision-making units (DMU) that in this technique using of multiple input and multiple outputs is possible. In the DEA model efficiency of (DMU) calculate by making of appropriate linear programming models. In this paper we consider fuzzy DEA (FDEA) based on (1 - a) statistical confidence interval and transform it to interval linear programming problem and solve themeʹs with Noorʹs method and a solution is present for the solve the problem in over the confidence interval of (1 - a) level. We will use the new ranking method discussed in this paper to ordering DMUʹs. We will give example and solve them.
